Both are technically true ;-). The MacPython DMG, and will continue to  
be, build agains the 10.4 SDK because 10.5 wasn't out when the latest  
release of Python was done.

PyObjC2 is slightly more complicated: it currently requires the 10.5  
SDK to build, but the architecture allows building on 10.4 as well.  
That support incomplete at the moment, patches would be more than  
welcome. What AFAIK needs to be done is implementing a number of C  
functions that emulate the Objective-C 2.0 runtime API. Most of that  
work is already done, and no rocket science is involved.

To be honest I believe this is a waste of time, what you'll end up  
with is a home-build version of python that is the same version as the  
system-installed one and misses a number of features. The resulting  
framework might run on 10.4 as well, but you don't know that without  
testing (AFAIK a number of unix API's that are used by the posixmodule  
have changed to be more in line with the current revision of the UNIX  
specificiation).
